Hello!

I'm continuing integration Noesis inside my proprietary OpenGL engine, all problems with state management was been fixed, but now I got one more phantom problem - after a random time after View rendering begin (like 1-2 minutes), it looks like elements broken (Text, Custom Elements, but not the background or simply button).

Then, after some time, it can randomly back to normal and back to glitch again.

void NSUIView::Update(double secs) {
    if (!IsVisible()) return;

    m_PureView->Update(secs);
    m_PureView->GetRenderer()->UpdateRenderTree();

    OnUpdate();
}

void NSUIView::Render() {
    if (!IsVisible()) return;

    m_PureView->GetRenderer()->RenderOffscreen();

    glBindFramebuffer(GL_FRAMEBUFFER, 0);
    glViewport(0, 0, WindowWidth, WindowHeight);

    m_PureView->GetRenderer()->Render();

    glUseProgramObjectARB(0);

    OnRender();
}

How it looks:

How expected:

Noesis Version: 3.1.2

Will be glad for any tips.

Could you please share two RenderDoc captures (one without glitches and one with errors) ?

I assume this is using our GLRenderDevice, not a custom renderer right?

I have a problem with RenderDoc because it is required modern OpenGL Context Pipeline 3.2+, currently, my project uses 2+ (old pipeline) with extensions.
Please, maybe exist some other method to track problem reason?

Yes, all right, default GLRenderDevice.

I used Nvidia Nsight for capturing, it works, but while not handling how to save traces.

But, I got some interesting things.

Without glitch Color 0 buffer (after ~1 minute after render begin):

With glitch Color 0 buffer (after ~5 minutes after render begin):

Seems that the buffer does not clear as well and after time just getting overloaded?

Probably same issue as in viewtopic.php?f=3&t=2489

Make sure you are doing glColorMask(true, true, true, true) before clearing.

Tried:

void NSUIView::Render() {
    if (!IsVisible()) return;

    m_PureView->GetRenderer()->RenderOffscreen();

    glBindFramebuffer(GL_FRAMEBUFFER, 0);
    glViewport(0, 0, WindowWidth, WindowHeight);
    
    glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
    glClearStencil(0);
    glColorMask(true, true, true, true);
    glClear(GL_COLOR_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);

    m_PureView->GetRenderer()->Render();

    glUseProgramObjectARB(0);

    OnRender();
}

Result after short time is same:

Let me understand something, what buffer is the "Color 0 buffer" in the screenshots. It is not the framebuffer right?

As i can suppose - it is Offscreen.

I need to understand more. How is the XAML that is rendering this part of the UI (including the text).
